Incomplete data on plastic additives in life cycle assessments (LCAs) poses a significant barrier to achieving a circular economy for plastics. This resource management research insight is drawn from a 2024 study published in Journal of Industrial Ecology. Using Literature review and database analysis with 13,587 additives identified in the UN Chemicals in Plastics Report, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing with plastics, do not assume standard polymer data is sufficient; actively investigate and account for the environmental impact of all additives used throughout the product's lifecycle.
Additive Data Gaps Hinder Circular Plastic Economy

Key Findings
- 01Additives have historically been omitted from plastic granulate data and production processes in widely used LCA databases.
- 02Major LCI databases cover only a small fraction (1,209 out of 13,587) of identified plastic additives.
- 03Lack of transparency, limited availability of additive datasets, and data incompleteness are major barriers to including additives in plastic LCAs.
Application
Design takeaway
When designing with plastics, do not assume standard polymer data is sufficient; actively investigate and account for the environmental impact of all additives used throughout the product's lifecycle.
How to apply
When conducting a life cycle assessment for a plastic product, explicitly identify all additives used, research their individual environmental impacts, and seek out or create datasets for them if they are not present in standard databases.
Project actions
- 01When researching materials for your design project, look beyond the base polymer and investigate the role and impact of common additives.
- 02Consider how the inclusion or exclusion of specific additives might affect the recyclability or end-of-life options for your designed product.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive review of additive inclusion in a major LCA database.
- +Assessment of additive coverage across multiple prominent LCI databases.
- +Development of a tool to aid practitioners in identifying data gaps.
Limitations
It can be challenging to obtain precise additive formulations from manufacturers, and creating new LCA data for missing additives is time-consuming.
Reliability & validity
The reliability of the findings depends on the accuracy and comprehensiveness of the reviewed databases and reports. Validity is supported by the systematic approach to database analysis and the identification of specific data gaps.
Think critically
Given the significant data gaps in additive information for plastic LCAs, how can designers and engineers make informed decisions about material selection to genuinely promote sustainability and circularity?
Design Principles
"Holistic Material Accounting: Ensure all components of a material, including additives, are accounted for in environmental assessments and design decisions."
Understanding the full material composition, including additives, is crucial for accurate environmental impact assessments and for designing effective recycling and reuse strategies. Without comprehensive additive data, efforts towards a circular economy may overlook critical environmental hotspots and hinder the development of truly sustainable plastic products.
What This Means for Your Design
It's hard to know the real environmental cost of plastic products because we often don't know what additives are in them, and the tools we use for this (like LCA databases) don't have enough information about these additives.
How to use in your project
- 1.Reference this study when discussing the limitations of standard material data in your design project's environmental analysis.
- 2.Use the findings to justify the need for more detailed material research beyond basic polymer specifications.

Paragraph starter
The environmental impact assessment of plastic products is significantly complicated by the historical omission and current scarcity of data concerning plastic additives within widely used life cycle inventory databases. As highlighted by Logan et al. (2024), this data gap impedes accurate environmental accounting and the effective planning for a circular economy. Therefore, a comprehensive understanding of plastic product lifecycles necessitates a proactive approach to identifying and incorporating additive data, even when it requires supplementary research beyond standard database entries.
